Problem Two: Consider the cross-sectional shown in the figure below. The cross-section is reinforced with 3 bars 30M as shown. 1. Calculate the cracking moment using the exact moment of inertia. 2. Calculate the stresses in the concrete and steel when the moment is 0.75Mcr. 3. Ignoring the self-weight calculate the stresses in the concrete and steel when the applied load is P=30 kN. 4. A beam with a cross-section shown in the figure below spans 4 m and is subjected to a concentrated load, P, at mid-span (see figure). Considering the self-weight, calculate the minimum load, Pmin, that induces cracking.

Add a superscript to each component to indicate whether they are acting in the positive (+) or negative (-) direction b) Draw a position vector from the origin (0) to the tail (point a) of the force vector c) Break up the position vector into rx and ry components; show these components on the figure Add a superscript to each component to indicate whether they are acting in the positive (+) or negative (-) direction d) Calculate the "moment" of force F about the origin by multiplying F times its perpendicular distance from the origin (ry), and add the product of Fy times its perpendicular distance from the origin (rx). Assume that a counterclockwise rotation about the origin is a "positive" moment. Think of rx as a string connected to the origin. If you pull the string in the direction of d, will that cause a clockwise (-) or…

Problem 4: The two bars can deform elastically. They are pinned at point B. The length of AB is 400 mm, length of BC is 250 mm, areas of cross- section of AB and BC are both equal to 35 square millimeters, and modulus of elasticity for material of the bars is the same, and equal to 250 GPa. Angle between AB and the horizontal is 30 degrees. Showing proper coordinate system (positive and negative directions), a. Consider the first figure below. A vertically downward force Facts at pin B. If the horizontal component of the displacement of B is 0.25 mm, determine the magnitude of the force applied, the vertical component of the displacement of B, and the net displacement of point B due to the elongation of bars AB and BC.
